Lenovo ThinkPad X1 Carbon vs Samsung Series 9 NP900X3C vs Apple MacBook Pro ;Who is Better?

W.A.Khan,                                                                                                                                             25/4/2013,                                                                                                                                                                                                   Lenovo ThinkPad X1 Carbon                                                                                                                                                   Incredibly light for a 14-inch laptop, the Lenovo ThinkPad X1 Carbon is ruggedly built, and has a better keyboard than any ultrabook-style laptop, even Apple's MacBook Air.
But, For such an expensive laptop, battery life is just so-so. Consumer-friendly options such as HDMI are missing.
The bottom line: The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential.

But, The Series 9's way-too-high sticker price makes the MacBook Air look downright affordable by comparison; the flexy case design doesn't feel as good as the MacBook Air's, either.
The bottom line: The $1,649 Samsung Series 9 NP900X3A certainly won't be for every wallet, but this light, well-featured, and striking 13-incher is the closest the Windows world will ever come to a MacBook Air. However, its higher-than-the-Air price will be hard to stomach.

But, Not much else has changed: the price, battery life, and older, thicker appearance, however well designed, remain the same.
The bottom line: While the 13-inch MacBook Pro remains a well-built laptop, it's fallen behind the MacBook Air and Retina Display MacBook Pro in design, lacks higher-end upgrades, and feels too expensive compared with the competition.                          Specifications
